what is your opinion of using guys money when the guy is not working and just studying?

i have a best fren..she is just graduate from diploma..and her bf doing degree and not working..i invited her to join me for 6 days part time job..1stly she wanted and her bf told her..he will gives her $$ to spend every month and the guy is not rich also..i told my frens for my opinion its not good to use bf's money coz come to the end the $$ is from the guys parents..n he is not working will burden him..and ppl will gossip..(if the bf's parents finds out!)

i mean if use his $$ for movies and stuff its alright..but use it for montly allowance? will u all "sampai hati" to use it?
